Researchers crack an enduring physics enigma

For decades, physicists, engineers and mathematicians have failed to explain a remarkable phenomenon in fluid mechanics: the natural tendency of turbulence in fluids to move from disordered chaos to perfectly parallel patterns ...

Electromagnetic water cloak eliminates drag and wake

Researchers have developed a water cloaking concept based on electromagnetic forces that could eliminate an object's wake, greatly reducing its drag while simultaneously helping it avoid detection.

From the butterfly's wing to the tornado: Predicting turbulence

An old adage holds that the flap of a butterfly's wing in Brazil can trigger a tornado in Texas weeks later. Though chaos theory says it's basically impossible to compute exactly how that might happen, scientists have made ...

Sitting still or going hunting: Which works better?

For the kinds of animals that are most familiar to us—ones that are big enough to see—it's a no-brainer: Is it better to sit around and wait for food to come to you, or to move around and find it? Larger animals that ...
